GENTON P. HOLDEN, 0F JACKSON COUNTY, MINNESOTA.

COLTER.

Application filed November 2, 1916.

To all whom it may concern:

Be it known that I, GENTON P. HOLDEN, a citizen of the United States,residing in the county of Jackson and State of Minnesota, have inventedcertain new and useful Improvements in Colters; and I dodeclare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to new and useful improvements in colters and theprimary object of the invention is to provide a plow with a colter wheelbearing adapted to exclude sand, dust, and other matter and to providean easy revoluble bearing having an ample oil lubricating capacity.

Another object of the invention is to provide a device of this characterwhich is simple and durable in construction, inexpensive to manufacture,and one which will be very eflicient in operation.

With these and numerous other objects in view, my invention consists ofthe novel features of construction, combination and arrangement of partswhich will be hereinafter referred to and more particularly pointed outin the specification and claims.

In the accompanying drawings Figure 1 is a central vertical sectiontaken through the colter;

Fig. 2 is a vertical section on the line 2-2 of Fig. 1; and

Fig. 3 is a partial side elevation of the colter showing the manner ofattaching the fork to one of the boxes.

In describing the invention I shall refer to the drawing in whichsimilar reference characters designate corresponding parts throughoutthe several views and in which the numeral 1 represents the colterwheel, which is of the usual variety.

The wheel 1 is provided with bearing plates 2 secured to opposite sidesof the same by bolts 3. These bearing plates 2 are provided adjacenttheir inner ends with projecting hort stub axles 4 which are disposed inaxial alinement with an opening 5 through the center of the wheel. Theplates 2 are furthermore provided with inclined flanges 6 on theirperiphery which extend outwardly and upwardly, and diverge from theopposite sides of the wheel 1. These flanges 6 form an annular channelon each side of the wheel to receive the dirt, sand, etc., dropping fromthe colter and preventing the Specification of Letters Patent.

same from working down between the movable and immovable parts of thecolter. The colter is also provided with bearing boxes 7 disposed onopposite sides of the wheel in which the adjacent portions of the outerends of the axles 4 are adapted to rotate. These boxes 7 extend beyondthe outer ends of the axles 4 and have axial openings of reduceddiameter designated by the numeral 8 and are disposed in alinement withthe openings through the axles. The ends of the boxes are positionedadjacent or beyond the ends of the axles so that a space will be leftbetween these two parts to prevent bearing on the ends, and to place thebearing surface directly on-said boxes.

The bearing boxes '7 are provided with outwardly inclined flanges 9formed integrally with their inner ends, and said flanges terminatebelow the juncture of the plate flanges and plates and are disposed atapproximately right angles to the plate flanges, thus forming an'annularinternal chamber on an opposite side of said wheel between the plates 2and bearing boxes 7. Arranged inside of said internal chambers are theheads and nuts of bolts 3, thus it will be Seen that the inclinedflanges form a protective covering or chamber and prevent any dirt,dust, etc., from entering the bearing boxes.

The different parts-of the colter are secured together by a tie bolt 10having a head 11 at one end and locking nut 12 at the other, which ispositioned through the ends of the boxes, the axles, and the centralopening in the wheel. The stationary bearing boxes 7 have their outerends notched as shown at 15 so as to receive the ends of the colterforks. These forks have openings through their ends adapted to receivethe tie bolt 10, and when positioned as shown in Fig. 1 of the drawings,the bolt will project through the openings in the forks adjacent itsends, the head 11 of the bolt resting against one fork, while thelocking nut 12 rests against the other.

The stationary boxes 7 are provided with openings 13 in which areadapted to be positioned oil cups 14. By this means the hearing surfacebetween the boxes and the axles may always be kept well lubricated toprevent any undue wear upon the same.

Attention is particularly directed to the position of the stationaryflanges on the inner end of the boxes, with respect to the flanges onthe plates which rotate with the wheel. These different flanges arepositioned substantially at rightangles 'to each other, the plateflanges diverging outwardly in one direction from the colter wheel,while the flanges on the stationary boxes terminate below the jointureof the plate flanges and plates,and at a point beneath the extremity ofthe plate flanges. By this positioning, there will be no possibility ofdirt, sand, etc., entering between the bearing of the colter and fromworking between the movable and immovable parts of the same. Theseprotective flanges will also prevent weeds, etc., from being drawn intothe bearings when the plow is being used on wet ground.

From the foregoing description of the construction and operation of thiscolter, the manner of applying the same to use and the operation thereofwill be readily noted and it will be seen that I have provided a simpleand efficient means for carrying out the objects of the invention. 7

I claim:

1. In a colter, a wheel, plates securecl to the opposite sides thereof,said plates being formed with inclined flanges on the periphery thereof,said flanges extending outwardly and diverging from the opposite sidesof said Wheel, said flanges and sides of Copies of this patent'may beobtained for the wheel forming an annular channel on each side of saidwheel, bearing boxes on opposite sides of said wheel and plates, andconnected thereto.

2. In a colter, a wheel, plates secured to the sides of said wheel, saidwheel and plates having a series of alining apertures ar ranged adjacenttheir central portion, a plurality of bolts passing through saidapertures and securely holding said plates and wheel together, saidplate provided with inclined flanges on its periphery, said flanges andsides of said wheel forming an annular channel, bearing boxes onopposite sides of said wheel and plates, said boxes being provided withoutwardly extending inclined flanges, said flanges closely engaging theouter faces of said plates and forming a protective chamber, said boltsarranged in said chamber thereby being protectedand said bearing boxesalso being provided with a rectangular recess at the outer ends thereoffor the reception of ends of the colter fork.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
